Description
Hydroman® TJH30-50H4A Horizontal Bentonite Slurry Transfer Pumps for Tunnel Construction is exactly a role that pumped continuously bentonite into the excavation face of a tunnel boring machine (TBM), where it stabilizes unstable ground, balances pressure against groundwater, and transports excavated material back through the slurry circuit.
| Bentonite pumping doesn't operate in isolation — it works alongside a slurry treatment and separation system that removes excavated solids from the returning bentonite suspension so it can be reused. Coarse shakers, hydrocyclones, and dewatering equipment typically process the returning slurry, with centrifugal slurry mud pumps feeding the separation stages before the cleaned bentonite is returned to circulation. The horizontal slurry mud transfer pump and the treatment plant function as a closed loop, and the reliability of one affects the performance of the other. |  |
Where used the Hydroman TJH30-50H4A Horizontal Bentonite Slurry Transfer Pump？

▪ Settlement tanks and slurry circulation systems
Hydroman® TJH30-50H4A Horizontal Bentonite Slurry Transfer Pumps Typical Applications in Tunnel Construction
▪ Slurry-supported TBM tunneling, delivering bentonite continuously to the excavation face to balance earth and water pressure in soft or water-bearing ground
▪ Annulus and tail grouting, where bentonite is used ahead of cement-based tail grout to provide immediate support around segmental tunnel lining
▪ Pipe jacking and microtunneling, lubricating the pipe exterior with bentonite as it is jacked through the ground to reduce friction
▪ Diaphragm wall construction, stabilizing trench walls during excavation for foundation and retaining structures
▪ Horizontal directional drilling (HDD), supporting borehole stability during long directional bores for utility and pipeline installation
